  • What is PHPA mud?
  • PHPA is used as a functional additive in water-based drilling fluids. The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability. We have several grades to offer to meet our client’s need with variants.
  • Can PHPA mud be used offshore?
  • In North Sea applications, PHPA muds are being used offshore The Netherlands successfully and routinely. However, poor results were obtained in offshore Norway and U.K. applications because of formation reactions, inadequate mixing and solids-control equipment, and general inexperience with water-based muds.
  • How does PHPA mud control shale?
  • For shale-control, PHPA can supposedly seal microfractures, coat shale surfaces with a film that retards dispersion and disintegration. The viscosifying effect of the dissolved high molecular weight polyacrylamide polymer controls the rheological behavior of the PHPA mud.
  • Can you drill cement with PHPA mud?
  • Do not drill cement with PHPA muds, unless the system will be replaced after drilling out, because PHPA muds are sensitive to high pH, especially in the presence of high calcium levels. If drilling cement with a PHPA system is unavoidable, pretreat the system with 0.251bmlbbl [0.7 kg/m3] sodium bicarbonate.
